I’ve noticed that a lot in videogames it’s the little things that bring animations to life. A character might be talking and some seem to only focus on moving the lips to mouth the words. There is no movement in the face outside of that. There arms are stiff as a board and don’t move while they speak. There is no expressing on the face, eyebrows, or anything else. The fine details where missed that make it feel and real.

It is quite interesting all the muscles that end up moving to form a simple word. What someone is doing with their hands. What other expressions the body is saying with what that person is speaking.
